IPC: H02M3/335
Filed: 2000-11-15
Abstract: PROBLEM TO BE SOLVED: To improve a power conversion efficiency and to reduce a power loss for maintaining a voltage constant by a cross regulation of a low DC output voltage. SOLUTION: A switching power source comprises a so-called composite resonance type switching converter having a primary side resonant circuit for forming a voltage-resonant converter at a primary side and a secondary side resonant circuit having a secondary winding and a secondary side parallel resonant capacitor.

Title: Heat utilizing system utilizing hydrogen storage alloy
Inventor: MARUHASHI TSUTOMU
IPC: F25B17/12
Filed: 2000-11-30
Abstract: PROBLEM TO BE SOLVED: To solve the problem that damage could be caused by a water hammer ing phenomenon or a liquid pressure wave similar to the phenomenon in a heat medium passage when a means for temporally stopping the flow of the heat medium at the time of switching the heat medium is employed for the purpose of preventing the mixing flow of the heat medium from being caused in the interior of a heat medium switching valve. SOLUTION: The heat medium is allowed to bypass each heat exchanger and the heat medium switching valve 29 by opening a bypass passage 40 from before the start of switching the medium until after the completion by use of the switching valve 29. Because the heat medium is not allowed to flow to the valve 29, the mixing flow of the medium cannot occur in the interior of the valve 29. Because the medium flows through the bypass passage 40 while the valve 29 is being switched, the flow of the medium is not stopped so that any liquid pressure wave such as the water hammer phenomenon or the like does not occur in the heat medium passage.

Title: Gas detector and gas detection method
Inventor: OZAWA TAKASHI
IPC: G01N27/12
Filed: 2000-12-01
Abstract: PROBLEM TO BE SOLVED: To detect a lowered concentration of gas components generated in case of a fire at a higher sensitivity than do gases such as carbon monoxide and methane and furthermore, identify gases and ethanol turned to miscellaneous gases generated during the fire individually with one gas sensor. SOLUTION: A heater drive circuit 5 generates a pulse drive signal in which the total of the ON operation time and the OFF operation time is equivalent to the cycle thereof as obtained when both of the operation time are repeated alternately a plurality of times and each ON operation time during the cycle has the almost same value whereas the OFF operation time during the cycle has a value that is longer enough than each ON operation time while differing from each other and performs an ON drive or OFF drive of a gas sensor 1 by the pulse drive signal. A sensor output detection part 13 detects a sensor output value from a sensor element 3 at each ON operation time during the cycle and a gas identification part 15 identifies the type of gases based on individual sensor output values.  As each OFF operation time is long enough, the sensor sensitivity increases to a lowered concentration of the gas noted in case of the fire to allow the identifying of the gas from a methane gas during the fire. Since the value of the OFF operation time differs from each other, there is a difference between the individual sensor output values depending on gases thereby enabling the identification of the type of the gases.

Title: Pressure reducing valve
Inventor: HORI HIDEJI
IPC: F15B13/042
Filed: 2000-12-01
Abstract: PROBLEM TO BE SOLVED: To provide a pressure reducing valve not reducing a controlled flow rate with a mechanism to roughly offset bi-directional thrusts each other by generating the opposite directional thrust matching to a secondary pressure in order not to obstruct a lever operation when the operating force of the lever is increased by unidirectional thrust generated by the secondary pressure, in comparison with a conventional pressure reducing valve without the mechanism. SOLUTION: This pressure reducing valve receives against the secondary pressure and a pressure to either of the two secondary pressure, which oppose each other, via a piston from the outside. Accordingly, the reducing valve has spools moving in holes set in a block. The secondary pressure, corresponding to the moving amount of the spool, is reduced from a primary pressure. Furthermore, in the reducing valve that outputs arbitrarily, either of the two secondary pressures receives not a spool but the piston (52) via a channel (15) that is set in the block (41) to communicate from the secondary pressure side to the piston (52).

Title: Chair and desk
Inventor: MORIHARA NOBUKAZU
IPC: A47B7/02
Filed: 2000-12-04
Abstract: PROBLEM TO BE SOLVED: To provide a chair and a desk with an improved stability. SOLUTION: A pair of inverted U-shaped leg-frames 24a, 25b are connected by middle connecting units 26a, 26b, a front-leg connecting unit 27 and a rear-leg connecting unit 28. If one of the following of the chair, i.e. width, depth or height to the seat, is at least to be changed, instead of changing the whole structure supporting a seat bottom 29, only a change of a corresponding unit among the leg frames 24a, 24b, the intermediate connecting units 26a, 26b, the front leg-connecting unit 27 or the rear-leg connecting unit 28 in its size is required, so that there is no waste of a material in changing of a size.  Besides, since the front-leg connecting unit 27 is connected to the bottom ends of each front leg 22a, 22b almost at the right angles and the rear-leg connecting unit 28 is connected to the bottom ends of each rear-leg 23a, 23b also almost at the right angles, a stability is improved with its efficient placement length being bigger when a seat 21 is placed on a floor. Furthermore, by fixing a desk-top instead of the seat bottom 29 on the middle connecting units, a desk with an improved stability becomes practical.

Filed: 2000-12-05
Abstract: PROBLEM TO BE SOLVED: To generate an assist force corresponding to a variation of a viscous friction, etc., in a device without impairing a reaction force information from a road surface in a power steering device. SOLUTION: A force (external force) other than a force for carrying out a steering (steering force) of a force acted on a steering device of a vehicle (action force) is calculated by an external force calculation part 78. On the assumption that this external force comprises an external force imparted from a road surface such as a SAT(self-aligning torque) and an internal resistance force caused by a viscous friction, etc., generated in the device, these two forces are separated by an external force/internal resistance force calculation part 86. At the time of the separation, the external force is defined as a function of an angle of side-slip and the internal resistance force is defined as a function of a steering angular velocity to determined a coefficient of the functions.  A motor control part 88 controls a motor based on the calculated internal resistance force to generate an appropriate assist force.
